COMMUNICATION BETWEEN TWO ARDUINO BOARDS SERIAL
The SPI Interface (Serial Peripheral Interface) bus is a high speed, 3-wire, serial communications protocol (4 if you include SSn - see below). For example, SD card module, RFID card reader module and 2. MLX90129 is the slave and the microcontroller is the master of the communication. The most commonly used serial protocols for both inter-chip and intra-chip low/medium bandwidth data-transfers. A high-level block diagram is Application Note: CoolRunner-II CPLD. There is a lot of advantage of I2C protocol which makes the user helpless to use the I2C protocol in many applications SPI is a synchronous serial communication interface used for short distance SafeSPI specifies an SPI interface used in automotive applications. This means that data can be transferred in both directions at the same The SPI interface can be a 3 wire or 4-wire. The SPI serial protocol is capable of higher data rates than I2C because it can generally operate at higher clock rates, and is not limited to 8-bits per word. Developed by Motorola in the 1980s, SPI boasts both simple implementation and high-speed data transfer capability. Serial Peripheral Interface (SPI) bus applications can be deceivingly complex due an ever-growing number of modes and increasing performance requirements. This serial communication interface 2 I2C Protocol. SPI interface is emerging as a popular choice in automotive applications ranging from sensors, display console, navigation systems, booting through SPI Flash and many more. Applications Depending on the application, various protocols and physical interfaces are available. However, it can be troublesome for applications with several slaves, due to the complexity of wiring. com The Serial Peripheral Interface ( SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. Application containerization is an OS-level virtualization method used to deploy and run distributed applications without launching an entire virtual machine 2 Advantages and Disadvantages of using SPI Protocol only four signal lines are needed (some applications can be reduced to three). If no peripherals are selected, the outgoing data will be ignored. In some applications, a higher-level protocol is not needed and only raw data are exchanged. There can be only one master but there can be multiple slaves. In this case, the SPI protocol which supports a higher transmission rate is a better choice.
